Climbing rose plant named &#39;Meivaleir&#39;

ABSTRACT

A new and distinct variety of rose plant is provided which abundantly forms attractive double blossoms having a luminous yellow-orange coloration. The plant exhibits a climbing growth habit, dense medium green semi-glossy foliage, and good vigor. The attractive medium green foliage contrasts nicely with the light-colored blossoms. The new variety is particularly well suited for growing as attractive ornamentation in the landscape such as in parks and gardens.

SUMMARY OF THE INVENTION

[0001] The new variety of Rosa hybrida Climbing rose plant was createdby artificial pollination wherein two parents were crossed whichpreviously had been studied in the hope that they would contribute thedesired characteristics. The female parent (i.e., the seed parent) ofthe ‘Meipalsar’ variety (non-patented in the United States). The maleparent (i.e., the pollen parent) was the product of the pollination ofthe ‘Korwest’ variety (non-patented in the United States) and the‘Circus’ variety (U.S. Plant Pat. No. 2,074). The parentage of the newvariety can be summarized as follows:

(‘Meipalsar’×(‘Korwest’×‘Circus’).

[0002] The seeds resulting from the above pollination were sown andsmall plants were obtained which were physically and biologicallydifferent from each other. Selective study resulted in theidentification of a single plant of the new variety.

[0003] It was found that the new variety of rose plant of the presentinvention possesses the following combination of characteristics:

[0004] (a) exhibits a climbing growth habit,

[0005] (b) abundantly forms attractive double blossoms having a luminousyellow-orange coloration,

[0006] (c) forms dense medium green semi-glossy foliage that contrastswell with the light-colored blossoms,

[0007] (d) exhibits good vigor, and

[0008] (e) is particularly well suited for growing as attractiveornamentation in the landscape.

[0009] The new variety well meets the needs of the horticulturalindustry and can be grown to advantage in parks and gardens.

[0010] The new variety has been found to undergo asexual propagation inFrance by a number of routes, including budding, grafting, and cuttage.Asexual propagation by the above-mentioned techniques in France hasshown that the characteristics of the new variety are stable and arestrictly transmissible by such asexual propagation from one generationto another.

[0011] The new variety has been named the ‘Meivaleir’ variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

[0012] The accompanying photograph shows as nearly true as it isreasonably possible to make the same, in a color illustration of thischaracter, typical specimens of the plant parts of the new variety. Therose plants of the new variety were two years of age and were observedduring June while budded on Rosa froebelli understock and growing inoutdoors at Le Cannet des Maures, Var, France. Dimensions in centimetersare indicated at the bottom of the photograph.

DETAILED DESCRIPTION

[0029] The chart used in the identification of the colors is that of TheRoyal Horticultural Society (R.H.S. Colour Chart). The description isbased on the observation of two year-old plants during June while buddedon Rosa froebelli understock and growing outdoors at Le Cannet desMaures, Var, France. The coloration in more common terms precedesreference to the chart in some instances. Such terminology is to beaccorded its ordinary dictionary significance.
